Powerlase Ltd. has announced the development of a 400G laser for green laser annealing (GLA) in AMOLED screen manufacture.

The laser products developed by Powerlase are designed in line with specific customer requirements. The 400G has been developed and tested in cooperation with one of the leading display screen manufacturers and is now entering the final development phase before being implemented in high volume manufacturing facilities.

"The introduction of GLA to the AMOLED screen manufacturing process has streamlined AMOLED production. The ELA it replaces, although functional, has a high cost of ownership. Currently, the running costs of the ELA equipment is about US$600,000 per year. This equates to a process cost of ~US$10 per glass sheet. GLA is predicted to be considerably more cost effective than this," said Mr Jung, from Dukin Co. Ltd.
